[Even if it is her first time making a sandcastle, it doesn't make the idea of a picture any more appealing.]

Well just as well I came prepared for such an occasion~

[If she's going to make it seem believable that this sandcastle thing is fun, might as well play the part right. In a few seconds a long stemmed plant with thin, tube-like flowers (http://www.desertusa.com/mag98/nov/papr/photos/chuparosa.jpg) sprouts from the sand. Plucking the plant from the ground, she pushes it into the top of one of the towers.]

By no means is a chuparosa any substitute for a flag, but perhaps it will be sufficient to make up for the lack of the real thing.
